Abstract: Tight oils have become important succeeding resources in Songliao Basin. In order to make sure of the resources potentials and distributions, and moreover effectively guide the tight oil exploration, the resources evalua-tions were conducted for the tight oil in Fuyu reservoirs. According to the explored degrees of the tight oil in the study areas, with the help of graded-resource-abundance analogy method and cell-based/small-bin volume method, on the bases of the geological characteristies and reservoir petroleum accumulating conditions, the classifications were performed for the evaluating units in the light of the reservoir physical properties and oil-bearing property/ oil contents, and furthermore the resources were calculated for Fuyu tight oil. The achievements show that the geolog ical resources of the tight oil are ranged from 10. 5x10° t to 11. 15x10°t, mostly contributed by Type-I Resources which are about twice as many as Type-II Resources; the resources decrease as follows: Sanzhao Sag>Daqing Pla-canticline>Longhupao Terrace>Gulong Sag>Chaoyanggou Anticline>Qijia Sag, of which resources Sanzhao Sag con stitutes more than 31% of the total, while Daqing Placanticline constitutes 27%. The researches prove that not only Sanzhao Sag and Daqing Placanticline are rich in the resources, but also the quality of the resources is much bet
